Arsenal must learn from their experience that three failed to win the EPL title even though they have a good game but sometimes they have difficulty scoring goals. So Rodrygo will be a very wise decision, especially Rodrygo players who have experience and he is able to face a difficult situation when the team needs victory. We can see Rodrygo under Ancelotti several times he managed to save Real Madrid from defeat.
And this will also be better for Rodrygo because it looks like Xabi Alanso is not so suitable for Strtagi that is applied by him at Real Madrid which makes it difficult for Rodrygo to get the main place in Real Madrid so he has a little minute playing. At Arsenal Rodrygo will definitely get a lot of playing time and this is good for Rodrygo's career in the future. I can say Rodrygo does not match Xabi Alanso's philosophy because in some matches Rodrygo always plays from the bench.
In my opinion, Rodrygo should stay at Real Madrid, he should be more patient, the league hasn't started yet and it seems to me that the new coach is still experimenting with the squad to have a definitive formation and players who will always be the ones to start the game. He probably still wants to see what the best position is for Rodrygo and Viciniu Jr. because both of them haven't been able to score goals consistently.
That is the point, some players are not patient they think they won't have space to play when the season start. So they prefer to leave before they miss the opportunity. Everyone knows that Rodrigo is a key player for Real Madrid and he as help the club many time to achieve there goals. I will prefer Rodrigo to stay and see if he will get the opportunity to play under xabi Alonso. I see many club as started requesting to sigh Rodrigo and am thinking that after the CWC he will make is decision for is future. And Arsenal are really ready to buy him to the club if he agree to move to the club. Let see is decision after the CWC competition. Xabi Alonso usually rotate payers and if Rodrigo will be calm and start next season with Real Madrid am sure he will get is space back if he perform very nice next season. Real Madrid are really ready to perform next season to challenge Barcelona to stop them win the laliga for the second term. Let see how the competition will go next season.
